wedi building board Technical data wedi building board General product description The wedi building board has a blue core made from rigid extruded polystyrene foam. The rigid foam is reinforced with glass bre (with alkali-resistant nish) on both sides and coated with a polymer-modied cement. Applications With its special properties, the wedi building board has a wide variety of applications: • Carrier element for laying tiles, slabs and natural stone oor coverings using the thin-bed method • Adhesive surface for applying plaster, tile adhesive and other materials • Moisture protection • Effective...

wedi building board Technical data Thermal insulation values of the building board Actual U-values incl. transition values When determining the U-value, only the wedi building board and the heat transmission resistances 1/␣i and 1/␣a for external walls are taken into account. In specic applications, the existing masonry and other layers must also be included.

wedi building board / building board Vapor Surface design Surface design Ceramic coverings Ceramic coverings offer various possibilities for wall and oor design. Depending on the intended use and personal taste, there is a wide variety of tiles and boards with different shapes, colours and materials. Here, the wedi building board is the perfect carrier element for ceramic coverings as the tile can be installed directly to the board surface without any additional steps needed. Plasters and llers Today, plasters are not only used for creation of a plain surface for tiling, painting or wallpapering,...

Technical data Natural stone coverings Natural stone coverings have a very particular air. They are made from natural stones and maintain their visual appearance as they are neither ground nor polished. This results in special characteristics such as the irregular colouration or pattern. wedi building boards are an ideal carrier element and allow for easy and fast installation. Laminates / ready-to-lay parquets Laminates and ready-to-lay parquets are an alternative to ceramic oor coverings. Laminate is a comparatively low-priced material that is only coated with a decorative layer; parquet is...

wedi building board Wall applications Sustainable surfaces When people refurbish old bathrooms which are in need of renovation, they often have to consider what to do with the old wall coverings, e.g. walls tiled to half height. wedi building boards offer simple solutions to this. The building boards most commonly used are the thicknesses 4 mm or 6 mm because they can be applied ush to adjacent tilework, leaving the tradesman with a clean, level surface to work with. wedi system components: • Clean the surfaces underneath before starting processing and, if applicable, apply a primer and level...

Wall applications Flush transitions to plasterboard wedi building boards with a thickness of 12.5 mm are a ush transition and very reasonable continuation of adjacent plasterboard surfaces in the splash water and wet areas of humid rooms. Contrary to common plasterboards, wedi building boards 12.5 mm – used together with the wedi Tools sealing tape – are impermeable to water and thermally-insulating, and do not require any additional waterproof coating. wedi building boards prevent the unpleasant feeling of cold walls in the shower area and reduce the build up of steam and condensation. wedi...
